I'd have loved to see the city streets at night. I thought the cemetery had more potential too.
Something that really bothers me is that if you turn down the chatter volume of the surrounding NPCs (because they can get loud and overwhelming in the city), it also turns down the voice volume of your companions when they have any party banter. That makes it very easy to miss interesting conversations/interactions that they have, or not notice it until they're already halfway through talking.
